Most often, 0x..050 is associated with dud RAM. That includes main memory, video and CPU cache memory. If you have more than one stick of RAM, start ripping the sticks out one at a time. If you only have one stick, you will need to find someone who can help you out with a spare stick that fits your machine.

If that doesnt work:

Disable all BIOS caching and speed-up options.
Disable power management.
If you are overclocking, don't.

If Windows starts to install, then BSOD's you will still have files on your HDD, format, run a scandisc (surface) before trying to re-install anything to check your harddrive is ok.

The error codes are memory or HDD read errors not CD-ROM read errors so my money is on your RAM.

1. Disable all caching on your computer, including the CPU cache and L2 cache, in the computer's CMOS settings. For information about how to use your computer's CMOS configuration tool, please refer to your computer's documentation.

If you can successfully install Windows after disabling all caching, try re-enabling each cache, one at a time, to determine the area in which the faulty RAM is located. If you still receive the error message, continue to the next step.

2. Temporarily replace your video adapter. If you can install Windows after replacing the video adapter, the video adapter you replaced is faulty.

3. Temporarily replace the main memory installed in your computer. If the RAM in your computer consists of multiple SIMM modules, you may be able to swap SIMM modules to determine which has the faulty memory.

For example, if you have four modules of 8 megabytes (MB) each, remove two of the modules and try installing Windows again. If the Setup process still does not succeed, swap one of the SIMMs in the computer with one that you removed and try again. Continue this process to determine which of the SIMM modules contains the faulty memory.

Right, but that's what I was asking how to do -- As in I don't have the client's computer's documentation. However, I just looked all through BIOS, but I didn't see any settings whatsoever for cache enabling...or anything to configure CMOS.

Re: Page Fault Preventing OS Install

Originally posted here by AngelicKnight I can't get Windows to install. When I try to do a clean install, I get a blue screen with this message:

PAGE_FAULT_IN_NONPAGED_AREA

and then:

STOP: 0x00000050 (0xC25E9001, 0x00000001, 0x809904F2, 0x00000000)

Tried rebooting and running the install again, but I wind up on the same darn blue screen.

Almost certainly a hardware fault (or a damaged CD). Try swapping RAM if you can (or remove half at a time if there's multiple sticks), or use Memtest86+ to check it. Other than that, remove any non-essential devices and see if it works.
